🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with distinct mechanisms. Gentamicin, an aminoglycoside antibiotic, binds irreversibly to the 30S ribosomal subunit of susceptible bacteria, interfering with protein synthesis and leading to bacterial cell death. It is effective against many gram-negative and some gram-positive organisms. Dexamethasone, a synthetic glucocorticoid, binds to intracellular glucocorticoid receptors, which then translocate to the nucleus and modulate gene expression. This leads to reduced production of inflammatory mediators such as prostaglandins, leukotrienes, and cytokines, and suppresses migration of inflammatory cells. Together, they treat bacterial infection while controlling the inflammatory response in the eye.

Dosage Information
| Adult Dosage | The usual adult dose is one to two drops instilled into the affected eye(s) every 4 to 6 hours, or as directed by your eye doctor. For severe infections, your doctor may recommend more frequent dosing initially, then reduce the frequency as the condition improves. The duration of treatment depends on the type and severity of the infection and inflammation. Typically, treatment should not exceed 7 days without medical reassessment. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician or eye specialist for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may be more susceptible to the side effects of corticosteroids, especially increased intraocular pressure and cataract formation. Use with caution and monitor closely. Dose must be individualized by a qualified clinician. |
| Renal Impairment | No specific dosage adjustment is established for ophthalmic use. However, if systemic absorption is significant, caution is advised in patients with renal impairment. Consult your doctor. |
| Hepatic Impairment | No specific dosage adjustment is established for ophthalmic use. Consult your doctor if you have severe liver disease. |
| Maximum Daily Dose | The maximum daily dose is not established from available information. Use only as prescribed by your doctor. |
